Dr. Clark's herbs and pregnancy

For the past 6 weeks I have been doing the kidney cleanse, bowel cleanse,and also parasite program. This past weekend I did my first Liver Flush with excellent results. Now this very minute I've found out that I'm pregnant. I'm going to stop the kidney program,and the fennel for the bowel. Any thoughts on the other herbs? Zapping is also no longer an option but Wormwood ? cloves? turmeric?and Cascara Sagrada?
I'm also curious about doing follow up liver cleanses, maybe without epsom. Any comments or experiences would be greatly appreciated! This will be my fifth child, the first four all born premature. This is a concern for me also. I took Colloidal Silver in my fourth pregnancy to prevent premature birth. Is there anything else that works? Robin Tweet
